外墙保温材料的发展前景是怎样

What is the development prospects of exterior wall insulation materials?

资源短缺是一个全球面临的问题,在这个时代背景下人们提出了建筑节能建议,其中保温材料就是建筑节能中重要的一员,国家也是制定了相关政策,可见我们国家对其中推广力度还是很大的。

The shortage of resources is a global problem. In this era, people put forward building energy-saving proposals. Thermal insulation materials are an important part of building energy-saving, and the state has formulated relevant policies. It can be seen that our country has made great efforts to promote them.

作为一种“好”的建筑物外墙保温材料,在具有良好的保温性能(极低的导热系数,的同时,还需同时具有较好的耐水性、较高的防火等级、极低的自重等特点。墙体保温材料的发展趋势与方向应包括以下几点。

As a kind of "good" building exterior wall insulation material, it has good thermal insulation performance (extremely low thermal conductivity, but also needs to have good water resistance, high fire prevention level, very low self-weight and other characteristics. The development trend and direction of wall insulation materials should include the following points.

1,外墙保温材料厂家应提高现有保温材料的耐水性。在常温情况下水的热导率是空气的23.1倍。保温材料吸水后不仅会大大降低其保温性能,而且会降低材料的耐久性。目前,大多数保温材料,尤其是无机材料,吸水率高,对外护层的防水要求十分严格,因此会增加外护层的费用所以,需要研究新型憎水剂并选择较合适的憎水剂在材料的生产过程中加入,以有效改变材料的表面特性,达到憎水效果。

1. External wall insulation material manufacturers should improve the water resistance of existing insulation materials. At room temperature, the thermal conductivity of water is 23.1 times that of air. After absorbing water, the thermal insulation material will not only greatly reduce its thermal insulation performance, but also reduce the durability of the material. At present, most thermal insulation materials, especially inorganic materials, have high water absorption and strict waterproofing requirements for external protective coatings. Therefore, it will increase the cost of external protective coatings. Therefore, it is necessary to study new hydrophobic agents and select suitable hydrophobic agents to be added in the production process of materials in order to effectively change the surface characteristics of materials and achieve hydrophobic effect.

2,外墙保温材料厂家应提高现有保温材料的防火等级。保温材料,尤其是有机材料的燃烧,不仅会造成环境污染,而且会对人体健康产生危害。因此,需要研究新型阻燃剂并选择较合适的阻燃剂在材料的生产过程中加入,以有效改变材料的阻燃性能。

2. Manufacturers of exterior wall insulation materials should improve the fire protection level of existing insulation materials. Thermal insulation materials, especially the combustion of organic materials, will not only cause environmental pollution, but also harm human health. Therefore, it is necessary to study new flame retardants and select appropriate flame retardants to be added in the production process of materials in order to effectively change the flame retardancy of materials.

3,发展多功能复合保温材料。目前,使用的保温材料在应用上都存在着不同程度的缺陷,无法同时满足保温隔热性能、耐水、防火等要求。因此,可以将具有不同特点的保温材料经过一定工艺复合在一起。例如,将岩棉和聚氨酯材料复合,使复合材料兼具A级不燃性和优良的保温性能。具体做法是将岩棉粘在水泥基纤维增强卷毡上并采用高压浇注机将聚氨酯树脂连续喷涂在岩棉表面,经层压机高温发泡成型,实现聚氨酯与岩棉的复合生产。

3. Develop multi-functional composite thermal insulation materials. At present, the thermal insulation materials used in the application of different degrees of defects, can not meet the requirements of thermal insulation performance, water resistance, fire protection and so on. Therefore, thermal insulation materials with different characteristics can be combined by a certain process. For example, rock wool and polyurethane materials are compounded to make the composites have both class A non-flammability and excellent thermal insulation properties. The concrete method is to adhere rock wool to cement-based fiber reinforced felt and spray polyurethane resin on the surface of rock wool continuously by high pressure pouring machine. The composite production of polyurethane and rock wool is realized by foaming at high temperature through laminator.

4,发展新型外墙保温材料。在现有墙体保温材料无法满足保温、防水、防火等要求时,研究发展新型保温材料。

4. Develop new insulation materials for exterior walls. When the existing wall thermal insulation materials can not meet the requirements of thermal insulation, waterproofing, fire prevention and so on, research and development of new thermal insulation materials.
